What ere Eddy currents and what is their application?
Eddy currents (also called Foucault currents) are currents induced in conductors, when the magnetic flux linked with a solid conductor changes. The change in magnetic flux can cause a circulating flow of electrons, or a current, within the body of the conductor.
The term eddy current comes from analogous currents seen in water.
